6 Claims.

My invention relates to a new and useful improvement in a gas burner adapted for mounting .on the exhaust pipe of internal combustion engines and is intended as a means for burning 5 carbon monoxide and other gases which are exhausted from internal combustion engines. An

object of the present invention is to render the operation of internal combustion, engines safer from the standpoint of exhaust gases.

It is another object. ofthe present invention to provide a device of this class which will be simple in structure, economical in manufacture, durable, easily and quickly assembled, and highly eflicient in use.

Another object of this invention is the provi- 1 sion in a device of this kind of an air delivery mechanism operated through theforce of the exhaust gases for delivering air to the mechanism.

Another object of the invention is the provi- 20 sion of a device of this kind in which air may be delivered into the burning chamber for mixing with the gases to be burned and in which additional air may be delivered into the mechanism for cooling purposes.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a ref- 30 erence to the accompanying drawing which forms a part of this specification and in which,

Fig. 1 is a central, longitudinal, horizontal sectional View of the invention.

In the drawing I have illustrated the inven- 40 tion attached to the exhaust pipe I of an internal combustion engine. This exhaust pipe communicates with a housing 8 having end walls 9 and I and provided with the partitions II and 12 to provide the separated compartments I3, 14, 45 and I5. Mounted in the walls}! and ID are bearings l6 and I! in which is rotatably journaled the shaft 18. Fixedly mounted on this shaft [8 lar turbine wheel 22 is fixedly mounted on the shaft l8 within the compartment I3. The compartment I5 is in communication with the atmosphere through the openings 23 formed in the end wall l0 so that air may be drawn into 5 the compartment l5 through these openings. The compartment 13 also communicates with the atmosphere through the openings 24. When gas is being exhausted through the pipe IT and the shaft [8 is being rotated air will be drawn into thecompartments and forced therefrom through the conduits 25 and 26 respectively, in the direction indicated by the arrows. The exhaust gas passes from the compartment or chamber, l4 into the conduit 21. This conduit extends through the end wall 28 of a housing 29 which is provided at its opposite end with the end wall 30. The conduit 21 is provided with the flared end of extension 3| which serves as an end wall for the housing 32. Positioned in this housing is a coneshaped partition or deflecting member 33 which is perforated and dished away from the concave end wall 34. This end wall is provided with an opening 35 at its center which registers with a central opening formed in the partition 35. This partition abuts against the perforated partition 36 which is mounted in the interior housing 31. This interior housing has an end wall 38 through which the conduit 21 extends. The housing 29 may be considered an outer casing and 30 the housing 31 the interior housing or casing. Extending from the partition 21 is the tapered. neck or conduit 38 which communicates with the perforated burning chamber 39 into .which projects the spark plug 40 which is mounted on the depressed portion 4| of the interior housing. The spark plug would, of course, be connected to a source of electrical supply. The'end of the interior housing is provided with the conical wall 42 which communicates with the outlet conduit 40 43. A screen 44 is positioned at the inner en of the conduit 43 and a similar screen 45 is positioned at the inlet end of the burning chamber 39. The conduit 26 extends through the end wall 28 and also through the end wall 38' so as to 45 communicate the interior of the housing 31 with the atmosphere. The conduit 25 projects through the end wall 28 and-terminates at this end wall so as to communicate the interior of the housing or outer casing 29 with the atmosphere. The end wall 30 is provided with exhaust openings 46. V

In operation when. the internal combustion engine is operated the exhaust gases passing through the conduit 1 will, through their action 5 I on the turbin g wheel formed from the plates I9, eil'ect a rotation of the shaft l8. This will also effect a rotation of the turbine wheels 2| and 22. The exhaust gases will pass through the chamber 32 and thence, as indicated by the arrows 20, into the burning chamber 39. Air directed through the conduit 26 will pass around the chamber 32 and thus become heated to some extent. Thence a portion of this air will pass into the burning chamber 39 and mix with the gases directed thereto through the exhaust conduit.- This mixing of the air with the exhaust gases will facilitate combustion and render the device more efilcient, inasmuch as a more complete combustion will be eifected. A screen 45 serves as a means for mixing the air and gases and reducing to a certain extent their velocity so that the mixture will temporarily be lodged within the burning chamber 39 to be there exploded and burned. As the incoming air and gases are delivered the bumedgas will, of course, be exhausted through the conduit 43. At the same time air delivered through the conduit into I the interior of the outer casing 29 will circulate around the interior housing 31 and effect a cooling of this mechanism. This air used for cooling will escape through the opening 46 as indicated by the arrows.

I have thus provided mechanism whereby the exhaust gases may be burned and whereby the exhaust gases themselves may serve as a means for bringing into the mechanism additional air for mixing with the exhaust gas and additional air for effecting a cooling of the mechanism so as to thus render the device highly emcient and attain the purposes and objects sought.

While I have illustrated and described the,

preferred form of construction I do not wish'to limit myself to the precise details of structure shown but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
